The Green Hill thomasia is a low shrub approximately 40 cm in height with multiple delicate stems that appear to grow from a rootstock (CALM 2003). The leaves are flat, narrowly elliptic and 10 – 13 mm long by 5 mm wide. The inflorescence (arrangement of flowers) is a raceme typically consisting of three flowers. The ribbed calyx (collection of sepals) is mauve with a reddish purple base. The calyx is approximately 7 mm long and is divided for less than half its length into five obtuse arching lobes. The rounded petals and anthers are dark purple to black in colour. The species is inconspicuous when not in flower (CALM 2003).

Potential threats to the species are browsing by sheep (Ovis aries) firebreak and fence maintenance activities the influx of pollutants or nutrients into areas of habitat habitat loss and fragmentation leading to further isolation of subpopulations and reduction in the already limited genetic diversity of the species and too frequent fire (CALM 2003).
